First -- I do not believe this is a duplicate issue. I've searched for same or similar problems on SO extensively, and due to the nature of troubleshooting before asking, I believe this problem is unique. Facebook cannot grasp my og:image files and I have tried every usual solution. I'm beginning to think it might have something to do with https://...
